16 Claims.

This invention relates to towel cabinets of the type adapted to contain a so-called continuous towel, that is, a long length of towel, usually in roll form, which is adapted to be drawn outwardly through an opening in the cabinet in suitable lengths for drying purposes, and which lengths in turn are'subsequently drawn backwardly into the cabinet by a suitable take-up roll and wound thereby onto a rollei1 removably positioned within the cabinet; the said take-up roll being operative to wind up the soiled lengths of towel simultaneously with the outward withdrawal of the clean lengths of towel.

In this type of cabinet a so-called feed roll is usually provided which is positioned to be engaged and rotated by the towel as the latter is withdrawn from the cabinet and which feed roll is operatively connected with'the take-up winding roll through gearing or other drive trans- 20. mission to impart movement thereto for winding up the soiled towel, in the manner referred to, simultaneously with the movement of the feed roll as the latter is rotated by the outward withdrawal of the clean towel.

Inthis type of cabinet means are also usually provided for controlling or measuring the withdrawal of clean towel from the cabinet, one such means, for example, as that disclosed in Patent No. 1,839,721, Jan. 5, 1932 operating to automatically stop the feed roll at each revolution thereof and thereby the feeding of the towel. Also,

means, such as a pawl and ratchet, are usually provided for preventing reverse movement of the take-up winding roll and thereby an unwinding of the soiled towel from its supporting roll.

In order to assure the proper functioning of the feed and take-up winding rolls and also the proper guidance of the towel in its passage through the cabinet from the supply roll to the take-up roll for the soiled towel, various guide rolls and rods are provided in addition to the feed roll and the take-up winding roll over which the towel passes. In the initial loading of the cabinet, that is, the placing of the roll of clean towel therein and the leading of the front end of such towel over and about the several rolls in its passage to the take-up roll, it is desirable that the feed ,roll and the winding take-up roll, which are normally held against movement in a re- Verse direction, should be capable of free rotation in both directions; this being particularly desirable in eecting the adjustment of the proper length of towel loop at the exterior of the cabinet :for drying purposes. With such de- 55A .sideratum .in mind, it has been one. of the main (Cl. S12-3 8) objects of the present invention to provide an improved means for releasing the feed roll and the take-up winding roll upon the unloading of the soiled towel from the cabinet whereby to permit of their free rotation in both forward and re- Verse directions upon the subsequent loading of I the clean towel, and to thereafter restore the parts to normal position and operation upon the completion of the loading of the towel, such operations preferably being automatic.

Other objects and advantages `of the invention will be referred to in the detailed description of the invention `which follows.

In the accompanying drawings forming part of this specification,

Fig. 9 is an enlarged detail illustrating the method of loading the cabinet in threading the towel about vthe parts in its passage from the supplyroll to the take-up roller.

Fig. 10 is a sectional detail on the line 10-10 of Fig. 7, showing the stop bolt in its housing block on the end of the feed roll.

The cabinet, which .may be of any desired construction or design, is here shown as comprising an outercasing formed `in two sections, 2 and,

the Afront section being hinged atone of its vertical edges to the rear section, as at 4, whereby the casing may be opened to admit of ready access to the interior thereof.

Located within the casing adjacent its opposite ends are a pair of frame or bracket plates 5, 5 for the support of the towel controlling mechanism to be presently described. Located between these bracket plates is a shelf 6 for the support of the roll of clean towel t, this shelf being provided at its opposite ends with downwardly turned iianges 7 which are engaged by a tie-rod 8 carried by the end frame plates to support the shelf at its rear side, the shelf at its front side being supported by a second tie-rod 9 about which the edge of the shelf is bent for attachment thereto as shown. The shelf is inclined from a point adjacent its front side downwardly toward the rear wall of the cabinet as shown, whereby the roll of towed as it unwinds and becomes smaller will gravitate towards the rear of the shelf and maintain its position on the latter.

In the so-called loading of the towel in the cabinet, after the roll of clean towel is placed upon the shelf 6, its leading end (see Figs. 1 and 9) is passed over a guide roller 10 adjacent the front of the shelf, from thence downwardly about a second guide roller 11, from which it passes backwardly and upwardly to take a substantially three-quarter turn about the feed roll 12, which latter is journaled in the end frame plates 5, 5 adjacent the front wall of the cabinet. From the feed roll, the towel passes downwardly in front of an inset portion 13 of the front wall of the cabinet to a position below the latter, where it depends in loop form for convenient use, as shown in Fig. 1, from which point it extends upwardly through an opening 14 in the bottom of the cabinet, to the rod 8, here serving as a guide rod, and from thence around a winding roll 16 to the soiled towel roller 17, about which latter it is wound by said winding roll in a manner to be presently described.

In the operation of the cabinet, when a length of towel is withdrawn therefrom by the user, the frictional engagement of the towel with the feed roll acts to rotate the latter and thereby, through operative connection with the winding roll 16, correspondingly rotates the latter to draw up the soiled towel into the cabinet and wind the same upon the roller 17 which is yieldingly held against said winding roll. Any suitable drive transmission between the feed and winding rolls may be provided, that here shown comprising a gear 18 on the end of the feed roll driving a like gear 19 on the end of the winding roll through an intermediate idler gear 20.

The feed roll 12 is adapted to be automatically stopped at predetermined times during its rotation to thereby control the delivery of the towel by limiting its withdrawal to certain predetermined lengths. rhe means here shown for stopping rotation of the roll 12 as referred to, comprises a boit slidably mounted in a transverse bore 2S formed in a housing block or disk 27 fixedly mounted on the squared end 28 of the spindle which carries the feed roll; this bolt being freely slidable in the bore 26 for movement transversely of the roll and being limited in its sliding movement by the engagement of the spindle end 28 (see Fig. 10) with the end walls of an elongated groove 30 formed in the bolt.

When a length of towel is drawn from the cabinet, thereby causing rotation of the engaged feed roll 12, the bolt 25 will slide outwardly from the roll connected disk 27 under the action of gravity as it moves downwardly from a horizontal position, so as to project one end thereof beyond the periphery of the disk whereby it will be brought into contact with the underside of a stop device 35, as shown in Fig. 5, and so stop rotation of the feed roll and thereby further Withdrawal of the towel. Subsequently, to obtain another length of towel, the bolt is'released by the stop, in a manner to be hereinafter referred to, to permit a further rotation of the feed roll. As here shown, the movement of the bolt in the bore 26 of its housing block is suicient to permit the opposite ends thereof to alternatively project beyond the periphery of said block for engagement with the stop device whereby the feed roll will be brought to a stop at each one-half rotation thereof. However, if so desired, the bolt may be so formed as to project only at one end thereof beyond the block, in which event the roll will be stopped at each complete rotation, instead of at each one-half rotation as with the device here shown.

The stop device is slidably mounted to be positioned out of the path of the bolt, as shown in Fig. 1, whereby the feed roll will be free for continuous rotation in either forward or reverse direction, as may be desired in the loading of the cabinet; or to be positioned in the path of the bolt, as in Fig. 5, whereby to stop rotation of the feed roll at predetermined times as in the normal operation of the cabinet; or to be moved forward from the latter position to engage an end face 36 of the bolt and move the latter backward into its bore in the housing block, as shown in Fig. 6. This last movement of the stop device is effected manually, by means to be hereinafter described, following which and upon release by the'user the stop device is automatically returned to its normal bolt engaging position by a connecting spring 37, this latter connecting at one end with a pin 38 on the stop member and at its opposite end with a xed part of the cabinet.

rlhe stop device 35 is here shown in the form of a bar which is slidably mounted for horizontal movement by means of a depending bracket plate 40 on oneV side thereof having a horizontally elongated slot 41 in which the plate is engaged by a xed pin 42 carried by one of the frame plates 5, the slot 41 permitting of the desired horizontal movement of the stop device. As an additional support and guide for the stop device, the latter at its rear end extends loosely through an opening in a bracket 43 also fixed on the plate 5. The means for operating this stop device will be presently described.

Secured on the outer walls of the opposite frame plates 5 are vertically arranged guide members 50, providing guide Ways 51 therebetween, in which are slidably supported bars 52 formed at their lower ends with forwardly projecting arms or extensions 5B adapted to receive thereon the end journals of the roller 17 on which the soiled towel is wound. These bars 52 are yieldingly held in a normal raised position with the roller 17 in operative engagement with the winding roll 16 by means of springs 55 which connect at one end with bracket arms 56 on the bars and at their opposite upper endsA with xed pins 57 on the frame plates. The bars 52 are so positioned relatively to the winding roll 16 as to hold the towel roller 17 back of the vertical center of the latter, as shown in Fig. l, whereby said roller will be retained on the supporting arms 53 by the winding roll; and the arrangement of these supporting arms 53 with their free ends projecting to a position adjacent the front wall of the cabinet is such as to permit of the convenient placing of the towel roller in its operative position at the rear ends of said arms and its removal therefrom.

In the normal position of the parts preliminary to the loading of the cabinet, as shown in Fig. 1, the stop device 35 is held by the spring 37 to its rear inoperative position, i. e. out of the path of the bolt 25, with its rear end in contact with a suitable stop 60, here shown as the inner face of one of the guide members 50. In this position of the stop device the feed roll 12, as hereinbefore described, is free to rotate in either forward or reverse directions for convenience in the loading of the towel. The stop device at its rear end is formed with an inclined or cam surface 61 which, when the stop device is in its said rearward position, engages with a similar cam surface 62 formed at the lower end of a rib 63 on the adjacent towel-roller carrying member 52 (see Fig. 1). Now upon the completion of the loading of the towel and after a few preliminary windings of the towel on the roller 17, preferably effected by the withdrawal of a few lengths of clean towel over the feed roll, these windings acting against the winding roll 16 will cause a lowering of the roller 17 and its carrying bars 52 from the position of Fig. 1 to that of Fig. 3, and thereby act through the lowering of the cam 62 against the cam 61 to advance the stop device sufficiently to be engaged by the stop bolt, as shown in said Fig. 3. Thereafter, in the continued operation of the machine and as the result of a few additional windings of the towel, the stop device will be fully advanced to its operative position as shown in Fig. 5, after which and until the clean towel has been used up, the stop device will be maintained in its operative position by the engagement with its rear end of the front wall of the rib 63 on the bar 52 during' the lowering of the latter as caused by the increasing diameter of the roll of soiled towel, as will be understood by reference to Fig. 5.

Any suitable means may be employed for operating the stop device to effect the disengagement of the bolt 25 therefrom, by moving it endwise in the bore of its housing disk, as shown in Fig'. 6; the means here shown comprising a lever pivotally mounted on the journal of the feed roll with one end engaging an overhanging hook-shaped member 71 secured to the upper side of the stop device, as by means of the screws 72, and with its opposite or lower end 73 extending into a position opposite a push-button 74 loosely mounted for sliding movement in a bearing block 74 attached to the casing section 13, the outer end of the button being in convenent position to be reached by the user of the cabinet. Upon the release of the lever 70 following the bolt disengaging operation shown in Fig. 6, the stop device is automatically returned to its normal operative position, shown in Fig. 5, by the action of the spring 37.

As a means to prevent withdrawal of the soiled towel from its roller 17, the engaging winding roll 16 is held against reverse movement by means of a pawl 75 engaging a ratchet 76 xed on one end of said winding roll, as shown in Figs. 2 and 4. When the clean towel has been used up and wound upon the soiled towel roller 17, the lat-` ter with the supported towel is rolled forward on the supporting arms 53 and removed from the cabinet, following which the bars 52 are automatically raised by the connecting springs 55 from their lowered position, indicated by broken lines in Fig. 1, to their normal raised position with the upper edges of the brackets 56 thereon in engagement with the lower ends of the guide members 50, as shown in Figs. 1 and 2. When in such position, the cam surface 62 on the rib 63 will be above the cam 61 on the stop device and the latter will be in its rear inoperative position to permit free rotation of the feed roll in either direction. At this time it is desirable that the winding roll 16 should also be free for rotation in either direction. To effect this, the pawl 75 is carried by a bar 79 which is mounted at one end upon a pivot 77, attached to one of the frame plates 5, and at its other end rests upon a pin or projection 78 carried by the adjacent bar 52, the position of said pin 78 on the bar 52 being such that when the cabinet is unloaded and vboth bars 52 are in their raised position, as in Figs. 1 and 2, the pawl 75 will be held above and disengaged from the ratchet, whereby the winding roll, like that of the feed roll at such time, will be free for rotation in either direction in the loading of the towel. Subsequently, upon the lowering lof the bars 52 by the initial windings of the towel upon the roller 17, the consequent lowering of the pin 78 will permit the pawl 75 to again drop into its operative position of engagement with the ratchet 76, as shown in Fig. 4. This lowering of the pawl into engagement with the ratchet is effected by the lowering ofthe bar carrying the pin 78, taking place substantially simultaneously with the advancing of the stop device 35 to its operative position as effected by the lowering of the other or companion bar carrying the cam 62.

'Ihe lowering of the bars 52 will be substantially in unison because of the engagement therewith of the opposite end journals of the roller 17, but they Vare preferably connected for movement as a unit, and this is accomplished as here shown by means of a rod or shaft 80 journaled at its ends in the opposite frame plates 5 and provided adjacent its opposite ends with rigidly connected crank arms 81 having a pin and slot connection with the upper ends of said bars as shown.

During the winding of the soiled towel upon the roller 17 by the action of the vertically stationary winding roll 16 and the consequent lowering of said roller 17 and its supporting bars 52, the springs 55 connecting with said bars areput under increasing tension so that, when the roller 17 with the towel thereon is removed from the arms 53 of said bars, the latter would be snapped upwardito their normal raised position under considerable force by the reaction of said springs, with consequent shock and jar to the engaging parts, unless some provision were made to check or cushion the same. To do this, I provide pneumatic checking devices of usual construction,

suchas indicated at 83, which are mounted on the frame plates at 84 with their pistons 85 connecting through links 86 with the crank arms 81 which engage the said bars, as shown. With this construction, the return of the bars 52 to their normal raised position under the action of the springs 55 is effected without shock or jar to the parts.

The guide roller 11, which engages the towel preliminary to its passage about the feed roll 12 and which is positioned to cause the towell to engage a substantial portion of the periphery of said feed roll, is supported to yieldingly coact with the latter as a pinch roll for holding the towel in close frictional engagement therewith and also to be bodily movable relatively to said feed roll to open up a space therebetween for the ready passage of the towel in the loading of the cabinet. For such support of the roller 11, it is journalled in the ends of members 88, 88, pivotally mounted on the opposite frame plates and having extensions 89 carrying pins 90 with which connect one end of each of springs 91, the opposite ends of which latter connect with the tie-rod 9. These springs 91 act to yieldingly hold the members 88 with the supported guide and pinch roll 11 in a normal position of engagement with the feed roll. As a convenient way of supporting the adjacent guide roll 10, this is joui'- nalled in the upper ends of the extensions 89 of said members 3S. The latter being mounted at the outer sides of the frame plates, these plates are provided with elongated slots through which the roller journals extend, the slots for the jour-v nals of the roll 11 being indicated at 93 and those for the journals of the roll 10 being indicated at 94.

The roll 10 is supported adjacent the front end of the shelf 6 and preferably slightly above the latter (see Fig. 9) whereby it will act to main- -tain the roll of clean towel on its shelf and, after the roll of towel is substantially reduced in diameter through use and is drawn forward into contact with the roll 10 by reason of a sudden forward pull or jerk on the towel in withdrawing lengths of same, said roller in its rotation will act to throw the roll of towel backward onto its shelf and so prevent the same becoming caught or jammed between the end of the shelf and said roller.

In the loading of the cabinet, the front section 13 of the cabinet is thrown open to expose ,and render readily accessible the parts therein. This permits of the convenient placing of the clean towel on the shelf 6 and the threading of the "leading end of the towel to a point over or beyond the feed roll l2. At this point it passes through an opening in the front wall of the casing to its exposed position in front of the inset portion .1.3 of the casing. Because of this, it becomes necessary, or at least desirable, to close the front section 3 at such time. Therefore, in order to permit of the completion of the loading operation, as effected by bringing the end of the towel up into the rear of the cabinet and into operative engagement with the take-up roll, the said inset portion 13 is in the form of a door which is preferably hinged at its lower edge to permit of the same being swung outwardly, as shown in Fig. 8, to give access into the cabinet. After the end of the towel has been brought into engagement with the take-up roll, the hinged section 13 is then returned to its closed position with the towel depending in front of the same as shown.

Both the feed and winding rolls, 12 and 16, are

. preferably provided with a sanded surface to increase the extent of frictional engagement of the same with the towel, and it therefore becomes desirable to renew these rolls from time to time. As a convenient means for permitting of this, the frame plates, in connection with the feed roll, for example, are provided at their front edge with open-ended slots 95 (see Figs. 2 and 4) terminating at their inner end in enlarged seats 96 in which are seated journal boxes 97 to receive the end journals of the feed roll. With such means, the journal boxes may be removed endwise from their seats, following which the roll may be removed by sliding its journals outwardly through the open-ended slots. Similar slots 98 terminating at their inner ends in enlarged seats 99 containing endwise removable journal boxes 100 (see Figs. 3, 5 and 6) are provided for the winding roll.
